Official temperatures are measured using thermometer placed in shelters that are louvered and white; placed a few feet above the ground; and placed in the shade
Devices that measure temperature or a temperature gradient are known as thermometers (the degree of hotness or coldness of an object). Two crucial components make up a thermometer: (1) a temperature sensor that changes in response to changes in temperature, such as the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer; and (2) a way to translate this change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer or the digital readout on an infrared model). In technology and industry, as well as in meteorology, health, and scientific study, thermometers are frequently used to monitor processes.
Due to the adverse conditions of poverty and unemployment in the rural areas, people migrate to urban areas. In urban areas they find increased employment opportunities and better living conditions.
